Thanks for filing this bug in Ubuntu.

Could you please attach the mysql log files from /var/log/mysql/* ?

The service is failing to start, but the systemd logs are not enough to tell me why. I see some apparmor DENIED error messages, but I also get them on a fresh install where mysql starts up just fine, so it must be something else.
